How to use the PU expanding foam gun

1. Shake the foam can vigorously up to 20 times.

5. The foam outlet can be adjusted with the flow adjustment screw.

After using the foam gun

1. Leave the gun filled with foam after use. Always keep a can of foam on the gun.
2. Fully tighten the flow adjusting screw. Do not empty the gun. The gun must always be filled with foam, otherwise, the foam will harden due to moisture in the air.
3. Remove the can in an upright position (gun pointing up).

Use the foam gun again

1. Shake the can vigorously (keep hold of the gun).
2. Carefully remove the hardened foam from the tip of the nozzle with a small, sharp knife.

4. The gun is ready for use.
5. The release of foam can be controlled by the trigger of the gun.

Replacing the can of a foam gun

1. Check to see if the can is empty by pouring the foam into a dust container until no more foam comes out.

4. Immediately squeeze out the foam to fill the extension tube.

Cleaning the foam gun when idle

1. Unscrew the polyurethane foam can (keep the valve away from you).
2. Take a can cleaner and screw the can to the gun.
